The VALiDATe29 squirrel monkey brain atlas was created from MRI scans of 29 squirrel monkey brains. The atlas is currently comprised of multiple anatomical templates (proton density, T1, T2* weighted), diffusion MRI templates (fractional anisotropy, mean diffusivity), and ex vivo templates (fractional anisotropy and a structural MRI). In addition, the templates are combined with histologically defined cortical labels, and diffusion tractography defined white matter labels. The atlas was created by researchers at Vanderbilt University Institute of Imaging Science.
